On November 21, as an important event of 2021 China 5G + Industrial Internet Conference, the theme is & ldquo; 5G mine, the 5G + Mine Sub-forum is held in Wuhan.
Peng Honghua, president of Huawei 5G product line, published the topic of the topic of the underground communication network & rdquo;
He pointed out: & ldquo; Based on 5G DMN (Underground Mobile Communication Network) vision, the connection is extensive, the performance is extremely good, one network, the operation and maintenance is simple, Huawei proposes 5G DMN technology innovation direction, and constructs full flexibility , Fully inferiorly, fully integrated network, solve the key issues encountered in mini-transformation in mini-intensive transformation, and help build intelligent awareness, intelligent decision-making and automated intelligent system. & rdquo;
It is understood that the current ground communication is very mature and sustained as a wide range of large coverage scenes, 2G, 3G, 4G, and 5G mobile communication systems, but the mine and other underground scenes are relatively independent closed space, in radio transmission characteristics, network deployment And the safety, reliability, availability, etc. are unique.
In the intelligent exploration of coal mines, there are 4 challenges in the current underground communication network: the environment is complex, the performance challenges, and the multi-network coexistence and operational and maintenance.These four challenges have restricted the comprehensive intelligent development of mines, and it is urgent to use 5G to accelerate the number of intelligence transformations.
In order to better promote technical standards and industries, solve the challenges of mine intelligence, and can continue to develop long-term, China Mobile and Huawei propose 5G DMN innovative solution ideas.
The program provides remote coverage and large upstream capabilities through a low frequency integrated, a high-capacity, and accesss a variety of narrowband items through NB-IOT. The innovative solution has a far-over, large uplink, quasi-positioning, and large-scale four super capabilities, which can meet the needs of mines such as mines.
Peng Honghua said that 5G DMN redefines the underground mobile communication network and serves a comprehensive intelligent upgrade of the mine. In the future, three communication networks will be formed in the future.
